Executive Summary

Radio Frequency Identification (RFID) is slated to become a standard tracking and tagging system for various products chain management systems. Since more and more products become RFID enabled, a faster identification mechanism must be needed. The anti-collision algorithm is one of the basic mechanisms used to address the issue of multiobject identification. This paper firstly introduces the basics of the RFID and anti-collision algorithm in RFID tag system. Then, Field Programmable Gate Array (FPGA) implementation for this algorithm is presented by using software-based simulation. The design methodology and results are useful for designing and implementing a practical RFID system.
